How a girl's hair looks the day of her Junior Highschool or Highschool prom. It is usually in a fancy/formal looking up-do and must usually be done at a salon.

Any style of an up-do, such as a loose, high bun with several pieces of squiggly hair dangling, is considered prom hair, as well as any other formal style that has been salon perfected. Glitter gel is also commonly used to make hair sparkle.
